Profiles that read two repositories, a libretro port and its upstream, now prefix each citation with source or upstream, decided by which tree carries the cited value at its pin. The emulator pages use the word to tell libretro glue, emulator code as the port carries it, and the upstream emulator apart.

notes: |
|
|
Kronos is a Sega Saturn and ST-V arcade emulator by FCare, forked from
|
|
Yabause. Requires OpenGL 4.3 compute shaders.
|
|
|
|
Saturn BIOS search order:
|
|
1. {system}/kronos/saturn_bios.bin
|
|
2. {system}/saturn_bios.bin
|
|
3. {system}/sega_101.bin
|
|
4. {system}/mpr-17933.bin
|
|
First file found wins. Real BIOS required (HLE deprecated, only available
|
|
via kronos_force_hle_bios core option for debugging).
|
|
|
|
ST-V BIOS: {system}/kronos/stvbios.zip or {system}/stvbios.zip
|
|
MAME-style ZIP containing region-specific EPROMs. Kronos picks the best
|
|
match by game region and kronos_stv_favorite_region core option (EU/US/JP/TW).
|
|
|
|
ROM cartridges for KOF95 and Ultraman are auto-detected via game database
|
|
(db.c) and loaded from system_dir when the corresponding game is running.
|
|
|
|
BIOS loading: retro_load_game() at yabause/src/libretro/libretro.c:1601-1727.
|
|
STV blob table: BiosList at yabause/src/ctrl/src/stv.c:112-136.
|
|
ROM cartridge DB: yabause/src/utils/src/db.c:43-45.
|
|
|
|
Standalone supports MPEG card ROM loading (Video CD card). Disabled in
|
|
libretro port (mpegpath = NULL in yabause/src/libretro/libretro.c:1578).
